Good luck in convincing her not to breed! I would understand if she knew *completely* what to do, and she was doing it to better the breed, but just to make money, thats sad.
I came to this thread to pick up some advice, since I have a friend that is bound and determined to breed her Black Lab for "some extra cash". She doesn't even have papers on her dog, plus in the shelters where we live, there are pure Labs everywhere.
